# --description--

Add the class `two` to the second marker `div`, and add the class `three` to the third marker `div`.

# --hints--

Deberías añadir la clase `two` al segundo elemento marcador `div` en el `container` `div`.

```js
const containerSecondChild = [...document.querySelector('.container')?.children][1];
assert(containerSecondChild?.classList?.contains('two'));
```

Tu segundo marcador `div` debería tener las clases `marker` y `two`.

```js
const containerSecondChild = [...document.querySelector('.container')?.children][1];
assert(containerSecondChild?.classList?.contains('marker') && containerSecondChild.classList?.contains('two'));
```

Deberías añadir la clase `three` al tercer elemento marcador `div` en el `container` `div`.

```js
const containerThirdChild = [...document.querySelector('.container')?.children][2];
assert(containerThirdChild?.classList?.contains('three'));
```

Tu tercer marcador `div` debería tener las clases `marker` y `three`.

```js
const containerThirdChild = [...document.querySelector('.container')?.children][2];
assert(containerThirdChild?.classList?.contains('marker') && containerThirdChild?.classList?.contains('three'));
```
